› What is it?
Willow bark is the bark from several varieties of the willow tree. The bark has been shown to help relieve some mild discomforts. Willow bark contains a chemical called salicin that acts similar to aspirin.
› Health benefits
Studies on willow bark have varying effectiveness ratings in the following areas:
Back pain
Willow bark appears to reduce lower back pain. Higher doses seem to be more effective than lower doses. It can take up to a week for significant improvement.
Joint pain
Research shows that taking a specific product containing white willow bark extract and other ingredients for 8 weeks reduces joint pain. But taking this product doesn’t seem to help joint stiffness or function. More research is needed to determine effectiveness.
Osteoarthritis
Research on willow bark extract for osteoarthritis has produced conflicting results. Some research shows it can reduce osteoarthritis pain. In fact, there is some evidence suggesting that willow bark extract works as well as conventional medications for osteoarthritis. But other research shows no benefit. More research is needed to determine effectiveness.
